  abstract = {{T}his methodological paper is part of a companion modeling approach conducted in the {S}enegalese groundnut basin. {I}t aims to address two key aspects: (1) the process of co-constructing the model as it was carried out with local stakeholders, and (2) the use of calibration to account for abstract (non-measurable) elements that stakeholders needed to describe and evaluate their system effectively. {T}hematically, this study explores the interplay of social solidarity and agro-pastoral systems in the {S}enegalese village of {D}iohine, where communal fallow lands persist as a critical marker of socio-ecological resilience. {U}sing a co-constructed agent-based model, "{M}e {R}e {D}iem", we investigate the dynamics of soil fertility, population, and agricultural yields over 25 years, integrating local knowledge and ecological data. {O}ur findings highlight the central role of social solidarity mechanisms, such as parcel lending and food sharing, in stabilizing agro-pastoral systems under resource scarcity. {C}alibration of the model demonstrates its ability to reproduce historical dynamics and test alternative practices. {W}ithout solidarity mechanisms, the system collapses, revealing their indispensability for long-term sustainability. {T}his work underscores the necessity of collaborative modeling to bridge empirical data and local practices, fostering actionable insights for addressing soil degradation and demographic pressures.},
